COAL SLURRY SYSTEM

摘要

A slurry of liquified carbon dioxide and finely pulverized coal particles is provided in a mixing chamber and discharged from the chamber into a pipeline for conveyance to a power plant. The slurry is depressurized at the downstream end of the pipeline by movement through pressure reduction means so that it is decompressed non-adiabatically and the coal and gas particles are separated. The gas remains at a low temperature and is passed in heat exchange relationship with cooling water from the power plant cooling tower to lower the temperature of same and consequently increase the efficiency of the power plant.
